We have been using the Killer Innovation muzzle brakes with excellent results in the 5/8-24 thread and for the 6.5 AR's we just opened a .223 brake up. We also put one on a 26" .243 LBC. I was just on their website and saw that they now offer a 9/16-24 6.5 brake. There aren't many options for a 6.5 9/16-24 brakes out there and the price looked great. I imagine it's a introductory price? I am in no way affiliated with Killer Innovation, I like their brakes. Excellent brakes for shooting from the prone, off the bipod.
